Aim: One of the proposed solutions to reduce energy consumption is to use nature as a source of inspiration. Surveys show that a large part of energy consumption is related to buildings. Considering that the building facade is the boundary between the interior and exterior space, it should be well-designed to reduce energy consumption. One of the solutions is to use an intelligent shading device that controls the entry of daylight in a hot climate.

Method: This research, with its quantitative nature and simulation-modeling research method, has designed a kinetic shell in a building inspired by the movement mechanism of the Rafflesia to control the daylight of the building in the Shiraz climate.

Findings: The research findings indicate that the petals of the Rafflesia performed their opening and closing pattern in five consecutive movements and can act as a kinetic pattern or as a source of inspiration for the movement of the intelligent shading device of the building facade.

Conclusion: In the current research, the petals are considered with triangle geometry, which opens and closes from zero to 45 degrees at the top. In addition, according to the sun’s path from 7 AM to 7 PM, successive steps of opening and closing the flower take place, which can significantly absorb 20% of the radiation and 10% of sunlight hours. Therefore, the movement pattern of the Rafflesia in the hot and dry climate of shiraz has reduced radiation, which shows the optimal performance of the kinetic shading device.
